Abstract

A power tool including a motor and a rotatable spindle driven by the motor to hold and drive a first bit. There is a recess located on the spindle. The power tool also includes a removable chuck with a lock member and a locking collar. The locking collar includes a locking position in which the locking collar biases the lock member into the recess to retain the chuck on the spindle. The locking collar also includes a release position in which the lock members are able to exit the recess and the chuck is able to be removed from the spindle by a user. The locking collar is axially movable from the locking position to the release position.

Claims

1. A power tool, comprising:

a motor;

a rotatable spindle driven by the motor and configured to hold and drive a first bit;

a recess located on the spindle;

a removable chuck, the removable chuck including a lock member and a locking collar;

wherein the locking collar includes a locking position in which the locking collar biases the lock member into the recess to retain the chuck on the spindle;

wherein the locking collar includes a release position in which the lock members are able to exit the recess and the chuck is able to be removed from the spindle by a user; and

wherein the locking collar is axially movable from the locking position to the release position.

2. The power tool of claim 1, wherein the locking collar is biased towards the locking position.

3. The power tool of claim 1, wherein the locking collar moves in a direction away from the motor when moving from the locking position to the release position.

4. The power tool of claim 1, further comprising a bit receiving opening in which the first bit held by the spindle is received when the chuck is retained on the spindle.

5. The power tool of claim 1, wherein the chuck further includes a plurality of jaws configured to hold and drive a second bit.

6. The power tool of claim 1, wherein the removable chuck includes a connection shaft which holds the lock members.

7. The power tool of claim 1, wherein the lock members are ball bearings.

8. The power tool of claim 7, wherein the locking collar includes a plurality of ball bearing interlock projections which project radially inwardly and keep the lock members in the groove when the locking collar is in the locked position.

9. The power tool of claim 1, wherein the power tool has an axial length along a rotational axis of the motor and wherein the axial length is less than 25 mm.

20. The power tool of claim 1, wherein the locking collar includes a plurality interlock projections which project radially inwardly and keep the lock members in the groove when the locking collar is in the locked position.

10. A power tool comprising:

a motor;

a rotatable spindle driven by the motor and configured to hold and drive a first bit;

a removable chuck configured to hold and drive a second bit and including a locking mechanism having a locking position in which the removable chuck is locked to the spindle and a release position in which the removable chuck can be removed from the spindle;

wherein the power tool is operable to in a first mode in which the removable chuck is removed from the and the first bit is exposed;

wherein the power tool is operable in a second mode in which the removable chuck is locked to the spindle and the first bit is covered by the removable chuck;

wherein the power tool is configured to switch between the first mode and the second mode without removal of the first bit from the spindle;

wherein the locking mechanism includes an actuation member which is configured to move the locking mechanism from the locking position to the release position; and

wherein the actuation member is movable in an axial direction.

11. The power tool of claim 10, wherein the actuation member is movable in an axial direction along an axis of the chuck.

12. The power tool of claim 10, wherein, in the second mode, the actuation member moves away from the motor to move the locking mechanism from the locking position to the release position.

13. The power tool of claim 10, wherein the locking mechanism includes a shaft with a central opening.

14. The power tool of claim 10, wherein the spindle fits into the central opening.

15. The power tool of claim 10, wherein the actuation member is ring shaped.

16. A power tool, comprising:

a motor;

a rotatable spindle driven by the motor and configured to hold and drive a first bit;

a recess located on the spindle;

a removable chuck, the removable chuck including a lock member and a locking collar;

wherein the locking collar includes a locking position in which the locking collar biases the lock member into the recess to retain the chuck on the spindle;

wherein the locking collar includes a release position in which the lock members are able to exit the recess and the chuck is able to be removed from the spindle by a user;

wherein the locking collar moves axially away from the motor to move from the locking position to the release position; and

wherein the locking collar is biased towards the locking position.

17. The power tool of claim 16, further comprising a bit receiving opening in which the first bit held by the spindle is received when the chuck is retained on the spindle.

18. The power tool of claim 16, wherein the chuck further includes a plurality of jaws configured to hold and drive a second bit.

19. The power tool of claim 16, wherein the removable chuck includes a connection shaft which holds the lock members.
